FRED J. KLEIN, OF NEW YORK, N. Y.

PAPER-FASTEN ER.

To all 107mm 7'1 may concern 3e it known that I. FRED J. Know. a eitixen of the United States. and a resident of New York. in the county of New York and State of New York. have invented certain new and useful Improvements in Paperl asteners, of which the following is a specification.

This invention relates to paper fasteners and particularly to the type of :l'asteners known as pin fasteners which embody pins or tongues that are passed through the papers to be held. and their free ends then bent down tint on the surface of the file.

The object of this invention is to provide improved means for disposing of the free ends of the tongues or pins after they are bent flat on the file. The means heretofore employed for disposing of the said free ends have not been very successful, some of the devices being inconvenient and awkward to manipulate and others too expensive to be commercially practicable. In my improved fastener I have overcome these (lilticulties and have discovered a simple and easily operated means for securing the free ends of the tongues so that they do not proj ee-t from the file in an objectionable manner and thereby catch loose papers and other things when the file is in use.

In the accompanying drawing, Figure 1, is a longitudinal section of a fastener and its retaining member embodying the preferred form of my invention as applied to a file of papers. Fig. 2 is a plan of the same. Fig. 3 is a. transverse section of the retaining member. Fig. 4:, is a perspective of the type of tongued fastener usually employed. Fig. 5 is a'plan of a modified form of my invention. Fig. 6 is a transverse section of the same.

Like characters refer to like parts in all figures of the drawing.

Referring to Fig. 4., I have here illustrated the form of pin fastener I commonly use in connection with my improved devices, and it consists of a flat base or body 2 and pins or tongues 3 bent up at right angles to the body and which are adapted to be passed through the papers it is desired to file. I employ a retaining member or washer 4 having a base 5, WlllCh is provided with perforations 6 near each end and through which the pins or tongues 3 are passed after they are put through the papers.

Specification of Letters Patent.

Application filed November 29. 1911.

Patented July 8, 1913.

Serial No. 662,963.

ln the preferred form of my invention l provide ridges or (an'rugations. such as 7, near each longitudinal edge of the retaining member each ridge having a corresponding groove underneath it and at the inner side of each of these cormgations or ridges I form longitudinal perforations or slits 8, which are slightly greater in width than the thickness of the tongues 3. The tongues 3 having been passed through the papers and retaining member, stand at right angles to the face of both the papers and retaining member and are then bent down so as to be parallel with the upper face 9 of the retail ing member as indicated in Fig. 1. They are then bent sidewise, as shown in Fig. so as to enter the slits 8, by means of Wllieli they are held from springing or being bent upward away from the face 9 of the retaining rnen'lber 4.

H. will be seen that the free ends of the tongues 3 rest in the shallow groove between the two ridges or corrugations T and that there is little possibility of the tongues catching on stray papers and other things when a file bound with this type of fastener is in use. The ease with which the ends of the tongues can be. secured in the slits is apparent, and it is also obvious that the fasteners hold the papers more securely and with less chance of being loosened where this method of securing the ends of the tongues is employed.

The modification of my device shown in Figs. 5 and (5 differs from my preferred form only in having uplifted portions 10 formed in the base of the retainer which take the place of the longitudinal slits 8. These uplifted portions or hooks 10 are formed by punching up the metal from underneath until it is separated from the base on three sides and is attached to it by the fourth side only. A space is therefore left underneath, a little higher than the thickness of the tongues 3, which can then be easily slipped under the hooks 10 and held by them. The tongue holding devices can be placed on both sides of the retaining member or on only one side as desired, the gain with the first form being in greater convenience in placing the tongues in the slits and with the latter in economy of manufacture.

I claim 1. In a paper fastener, a member having a pair of tongues to be pushed through papers, and a retaining member over which posed position with its end under said trngue-holding edge? 2. A paper fastener comprising a member having two tongues adapted to be pushed through the papers, and a retaining member having two slots and having two ridges separated by a distance greater than the width of the tongue, one of said ridges having a tongue-holding edge for the purpose of holding the end of a tongue when said tongue is bent laterally under it, after being passed through the slots in the said iretaining member and laid fiat on said mem- 3. In combination with a tongued paper fastener, a retaining member embodying two longitudinal, parallel ridges, a tongue-hold ing edge in the inner side of one of said ridges and nearest to one end of the retaining member, a tongue-holding edge in the inner side of theother ridge and nearest the other end of the retaining member, and two slots between said ridges, one at each end of the retaining member.

Signed at New York in the county of New York and State of New York this 25th day of November A. D. 1911.
